Yii框架下安装xhprof

http://blog.csdn.net/willwcw/article/details/46696017

xhprof 是一款非常不错的php性能分析工具，由facebook开发，有直观的图形分析，可以看到各个流程的性能损耗。下面是在Yii框架下安装xhprof

1，安装xhprof

如果安装了php，很简单执行：pecl install xhprof 就可以了

否则找个靠谱的源 sudo yum install xhprof 也可以

2，配置php.ini

[php] view
plain copy

[xhprof]

extension=xhprof.so

xhprof.output_dir=/home/work/tmp/xhprof

其中oupput_idr 是输出文件的目录

3，安装libpng

wget http://nchc.dl.sourceforge.net/project/libpng/libpng15/1.5.1/libpng-1.5.1.tar.gz
tar zxf libpng-1.5.1.tar.gz

cd libpng-1.5.1

./configure

make

make install

或者直接sudo yum install libpng 简单

4 安装Graphviz

wget http://www.graphviz.org/pub/graphviz/stable/SOURCES/graphviz-2.24.0.tar.gz
tar zxf graphviz-2.24.0.tar.gz

cd graphviz-2.24.0

./configure --with-png=yes

make

make install

5 配置nginx

[php] view
plain copy

server {

listen 8088;

root /home/work/local/php-5.5.18/lib/php/xhprof_html;

location @php {

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME "$document_root/index.php";

fastcgi_pass php;

}

location ~ /robots\.(txt|php) {

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME "$document_root/robots.php";

fastcgi_pass php;

}

location ~ \.php$ {

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_pass php;

fastcgi_index index.php;

}

location / {

try_files $uri @php;

}

}

重启nginx , nginx -s reload

重启php-fpm , pkill -USR2 php-fpm, php-fpm

6 配置Yii框架下使用xhprof

找到protected目录下的yii.php

加入以下代码

[html] view
plain copy

public static function createApplication($class,$config=null) {

<span style="white-space:pre"> </span>$app->attachEventHandler("onBeginRequest", function() {

xhprof_enable(XHPROF_FLAGS_NO_BUILTINS);

});

$app->attachEventHandler("onEndRequest", function() use ($app) {

$data = xhprof_disable(); //返回运行数据

include_once "xhprof_lib/utils/xhprof_runs.php";

$objXhprofRun = new XHProfRuns_Default();

$run_id = $objXhprofRun->save_run($data, $app->name);

});

}



7 结束

打开你的任意网页，会在/home/work/tmp/xhprof目录下产生性能分析文件，之后通过localhost:8088/index.php就可以访问文件了，点击view_all_callgraph还可以看到直观的性能分析图。
